Unsteady MHD free convective viscoelastic flow and mass transfer through porous medium

Abstract

Analysis of unsteady two-dimensional free convective flow and mass transfer through an incompressible electrically conducting viscoelastic fluid in porous medium bounded by a vertical infinite surface with constant suction velocity and constant heat flux in the presence of a uniform magnetic field is discussed. The effects of Grashoff number,modified Grashoff number, Schmidt number, Eckert number, permeability parameter, phase angle and magnetic number on velocity, temperature and concentration profiles are discussed and shown graphically. Also effects of various physical parameters are considered on skin friction coefficient, Nusselt number and mass transfer coefficient at the surface.
